be fed backwardly around the platen; that is to say, all of the clips oneach side may be disengaged from the work-sheets by a have inclinedslots 32, vwhich engage pins` 33, secured to the sides or' the table 19.Each rail 31 is actuated by a common handle 34 against 'the tension of aspring 35, so that as the rail moves lengthwise, the calin slots 32 willlalso force it to move trans-` versely with respect to its lengtln,whereby it will engage the proJections 8O and-recit the clips 22 so asto raise theinin unison 'from their active positions, .indicated in Fig.3, to Ltheir` inactive positions, shown in Fig.I 2.

The utility of the device will be readily understood when ltaken inconnection with the above description.. In the example shown, there areprovided ledger, statement and invoice sheets. The feed rolls 5 arefirst released. Then the ledger sheet is inserted, top edge first, atthe rear of `'the its leadino' edge is drawn up on the table 19, un'tithe next blank line to be typewritten upon isv in register with' theupper edge oit the Opposite tcp side clips 22 (which will engage withthe top of the ledger sheet, as it is shown to be the highest o the'three sheets) (are brought in play, clipping the ledger .sheet to thetable 19. However, the sheet may in some cases be licld by a singleclip. The operative then has bo'th of his hands free to introduce andcollate the other worksheets in The statement sheet is positioncd uponthe platen after the insertion of an interleavingcarbon sheet, and isbrought to a position with its next line to be typewritten 'upon inregister witli'the guide-bar or rail 20. Then it is held on the table 19by means oi' the next lower opposite clips 22. The invoice sheet is thenpositioned in the saine manner, with the carbon sheet between it and thestatement sheet. rlhis sl. eet may also be secured to the collatingtable 19 by means of the third opposite clips 22. lt is obvious that theclips may be used in 'any order. Since each clip is of thin plate-likeor leaf-like term, it lies conveniently between the sheet-s if required.

The feed rolls 5- are then brought into lplay by an operation oi' therelease key-lever 12, so that the assembled work-sheets are gripped tothe platen 1. in their collated position, forming a set. The series ofclips onboth sides of the collatiiigr table can now be released by anoperation of the handle 34:

on the right-hand bar 31, which is connected by an extensible rod 31with the left.- hand bar 31. Each of these bars will swing all ot theclips on the corresponding side of the collating'r table 19simultaneously to in- 7.0'

active positions. lf any clip underlies a sheet, it will' readily clearitself therefron'i, beingv made short and of simple forni for thispurpose.

The collated pack oi' sheets can then be 75 fed bac-kwardly by a reverserotation of the platen 1, so as to bring the superposed lines, whichwere brought into register with one of the edges of the guide-rail 20,into register with the printing 'point of the typewrit- 80 ingr machineindicated by a type-bai' 35 striking` the platen 1 (Figs. 1 and 2); Thenormal typewriting operation can then take place. All of the clips 22 ill have their 'faces flush with or outside of the sides 25, so 85 thatthey will not interfere with the movement ofthe work-sheets as they areadvanced during a typewriting' operation.

rlChe feed-roll release mechanism may be connected to the handle 34 sothat when the Sil handle is operated to move the clips 22v toineffective position,' t-he rolls 5 will be set against the platen tohold the sheets against the platen. This may be Clone before the 'rails3l move the clips off from the sheets. 95

For this purpose, the connections between the handle 3% and thefeed-roll release mechanism may comprise a sleeve 35a secured to theusual arm 37 which is connected by link 11 to rock the shaft). Extendinginto said 100 sleeve 35a and connected to nieve therewith by a pin 38 isa shaft 39, to the other end of which is connected an arm 410. The arml() 'is connected by a link ,Ill to an extension upon the right-hand.rail 31. The vlink .V555

has a pin-and-slot connection est, fi-, with said rai 31, so that thefeed rolls may be released by the operation of the -k'ey l2 withoutaffecting' tliclclips, and so that ther clips inay be released withoutcasting,l the El@ feed rolls ,otl' the platen. lli/Then, however, thefeed-roll release lever is in' position to hold the rolls off from theplaten, Tas during l cellating, and the handle il'is operated, the

pin will engage the end of the slct'e, vllt and, tljirougli theconnections described, rock the shaft 9 to set the feed rolls againstthe platen. The sleeve has a slot into which extends the pin 38 on theshaft 39, to permit adjustment'of the chute in which the shaft-12S 39 ismounted,` without interrupting the connections between the handle 34 andthe teeni-oll release mechanism.

Each section of the table 19 is secured by nieansoiLl an ear 46 to anarm il? slidably 125 mounted on a rod,/l8,extending across thetypewriter carriage and mounted in the end plates 2 thereof. The upperend of the arm 47 -is forked to engage the supporting rc 21 mounted in abracket 49' secured to each 1,239

The sections et' the table and ehute are held afrainst movementrelatively to one an-y other by means of screws 5l which pass throughslots 22 el the rightehand section ofA the table 19, the screws beingthreaded into a portion of the leftdiand section of the eollating table19. When the sections olf the chute are inoved to and 'from one another,the feed rolls 5, which are slidably :mounted upon 'the shaft (l, movewith said sections because of the engagement of the *feed rolls "withthe side edges of open-4 inns in the chute Aprovided for the i lg/rolls,A screw ,may be provided upon the ends ol the shaft (i, to preventaccidental removal of' the feed rolls from the shaft.

The Vraging b ar 20 is of such' 'length as to prevent its removal fromthe slots 2,0l in the side of the paper table, when the tableV is fully*expanded. The gage bar is made of .springy material and is trietionallyheld in slots 120 because of the curvature of the slots.
